我有一个脚本，可以遍历一堆分隔的文本文件，并将这些文件中的图像上传到SharePoint网站。它工作得很好，但有一个小问题，我有几张大小超过4MB的图片，当脚本尝试上传它们时，会出现(400) Bad Request错误。
下面是代码：
class spImageUpload()
{
private static System.Collections.Generic.List<string> keywords;
private static NetworkCredential credentials = new NetworkCredential(username, password, domain);
private static ClientContext clientContext = new ClientContext(site name);
private static Web site = clientContext.Web;
private static List list = site.Lists.GetByTitle(listName);
private static FileCreationInformation newFile = new FileCreationInformation();
private static Image image = new Image();
private static FileIO fo = new FileIO();
public SharePointAccess()
{
sharepointLogin();
uploadImage();
}
private static void updateFields()
{
//Loads the site list
clientContext.Load(list);
//Creates a ListItemCollection object from list
ListItemCollection listItems = list.GetItems(CamlQuery.CreateAllItemsQuery());
//Loads the listItems
clientContext.Load(listItems);
//Executes the previous queries on the server
clientContext.ExecuteQuery();
//For each listItem...
foreach (var listItem in listItems)
{
//Writes out the item ID and Title
//Console.WriteLine("Id: {0} Title: {1}", listItem.Id, listItem["Title"]);
//Loads the files from the listItem
clientContext.Load(listItem.File);
//Executes the previous query
clientContext.ExecuteQuery();
//Writes out the listItem File Name
//Console.WriteLine("listItem File Name: {0}", listItem.File.Name);
//Looks for the most recently uploaded file, if found...
if (listItem.File.Name.Contains(fileName))
{
title = fileName;
//Changes the Title field value
listItem["Title"] = title;
//Changes the Keywords field value using the keywords list
foreach (var keyword in keywords)
{
listItem["Keywords"] += keyword;
//Writes out the item ID, Title, and Keywords
//Console.WriteLine("Id: {0} Title: {1} Keywords: {2}", listItem.Id, listItem["Title"], listItem["Keywords"]);
}
}
//Remember changes...
listItem.Update();
}
//Executes the previous query and ensures changes are committed to the server
clientContext.ExecuteQuery();
}
private static void uploadImage()
{
try
{
fo.loadFile();
foreach (var img in fo.lImageSet)
{
Console.WriteLine("Image Name: {0}", img.getName());
}
foreach (var img in fo.lImageSet)
{
DateTime start;
DateTime end;
start = DateTime.Now;
//Sets file path equal to the path value stored in the current image of lImageSet
filePath = img.getPath();
//Writes out to the console indicating what's been stored in filePath
Console.WriteLine("Image Path: {0}", filePath);
//Reads in the contents of the file
newFile.Content = System.IO.File.ReadAllBytes(filePath);
//Sets the file name equal to the name value stored in the current image of lImageSet
fileName = img.getName() + ".jpeg";
//Sets the URL path for the file
newFile.Url = fileName;
//Creates a List object of type String
keywords = new System.Collections.Generic.List<string>();
//For each keyword in the current image stored in lImageSet...
foreach (var keyword in img.lTags)
{
//...add that keyword to the newly created list
keywords.Add(keyword);
}
//Uploads the file to the picture library
Microsoft.SharePoint.Client.File uploadFile = list.RootFolder.Files.Add(newFile);
//Loads uploadFile method
clientContext.Load(uploadFile);
//Executes previous query
clientContext.ExecuteQuery();
//Calls the updateFields method to update the associated fields of the most recently uploaded image
updateFields();
end = DateTime.Now;
TimeSpan span = end.Subtract(start);
//Writes out to the console to indicate the file has finished being uploaded
Console.WriteLine("Uploaded: {0}", fileName + " Done!");
Console.WriteLine("Time Elapsed: {0}", span.Seconds + "seconds");
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
private static void sharepointLogin()
{
try
{
//Loads credentials needed for authentication
clientContext.Credentials = credentials;
//Loads the site
clientContext.Load(site);
//Loads the site list
clientContext.Load(list);
//Executes the previous queries on the server
clientContext.ExecuteQuery();
//Writes out the title of the SharePoint site to the console
Console.WriteLine("Title: {0}", site.Title);
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
}
现在，我必须使用客户端对象模型远程执行所有操作。 我无法使用SharePoint.Administration更改最大上传大小。 那么，有谁知道如何使用客户端对象模型解决无法上传大于4MB文件的问题吗？非常感谢您提供的任何帮助！
